Extend your chimney liner by one foot and prevent smoke crossover by mounting our Deluxe Terra Cotta chimney cap directly to the top of your Boost-a-Cap!

It’s easy to install. First, install the Boost-a-Cap. Second, insert the liner through the stainless connection strap on the base of the Deluxe Chimney Liner Cap and tighten. Tightening the connection strap provides a strong and clean connection without the use of screws that can pierce the liner. Then, simply mount the Deluxe Chimney Liner Cap to the top of the Boost-a-Cap by tightening the retention screws to create a strong, tight and reliable fit.

The cap is connected by a hinge to the built-in top plate. The hinge allows for easy cleaning of your chimney liner system.
